I work for NASA tracking the TDRS satellites. Formerly a member of the DSN tracking every satellite outside of Earth's orbit.
I’d rather a Log Horizon server but I get what you’re saying and I like where your head is at. Though that will probably mean there’ll be a .Hack server too. :p
Am I the only one to remember BBS’s? Many of them would run the same game but setup different rules based on which BBS you connected to. Having one large overworld in the multiverse is a great idea to provide access to all the custom shards while still all being connected to one greater multiplayer game.
Personally I’m looking forward to it.
